Parse error: syntax error, unexpected $end in /home/web/eee/encryption.php
on line 28


thanks

<?php

$plain_text = "{}[]:";'<>?,./`1234567890-=~!@#$%^&*()_+";

$password = "this is the password";

$initialization_vector = 11223344;

$encrypted_text = mcrypt_encrypt(MCRYPT_3des, $password, $plain_text,
MCRYPT_MODE_cfb, $initialization_vector );

echo $encrypted_text ;

?>

I don't know much about PHP, but I'd say the second " in this line
is misplaced. It should probably be escaped as \"

Above line belongs in the headers not in the message text.

In PHP, you probably want to use single-quoted string literals to
avoid variable substitution.
$plain_text = "$xyz";
will probably not evaluate to a string with 4 characters in it
unless $xyz has the right value.

Also, you need to escape special characters (like single quote)
inside such a literal that are supposed to be taken literally.

This seems to be a problem in your program even if you take out the
calls to do encryption entirely.
